I have been thinking of an 18 warlock/2 arti build intelligence based GOO. I want to be able to trap and have an easy button. Has anyone done this and enjoyed it? Is it worth going 17 warlock/2 arti/1 wiz for the extra feat? I would assume artificer level 1st for the skill points. I have done warlock 18/2 rogue which was ok but I feel like my charisma based life did more damage. Is this true or just my perception. Any help would be appreciated.
